I find it strange that GPT-5 is cheaper than GPT-4.1 in input token and is only slightly more expensive in output token. Is it marketing or actually reflecting the underlying compute resources?
- AS04 1y agoVery likely to be an actual reflection. That's probably their real achievement here and the key reason why they are actually publishing it as GPT-5. More or less the best or near to it on everything while being one model, substantially cheaper than the competition.
- ComputerGuru 1y agoBut it can’t do audio in/out or image out. Feels like an architectural step back.
- conradkay 1y agoMy understanding is that image output is pretty separate and if it doesn’t seem that way, they’re just abstracting several models into one name
- arresin 1y agoMaybe with the router mechanism (to mini or standard) they estimate the average cost will be a lot lower for chatgpt because the capable model won’t be answering dumb questions and then they pass that on to devs?
- low_tech_punk 1y agoI think the router applies to chatgpt app. The developer APIs expose manual control to select the specific model and level of reasoning.
